WARSAW, May 23 (Reuters) - The US ambassador to Poland

on Thursday criticised the country's broadcast regulator for

questioning the ownership structure of US company TVN Style.

TVN Style is owned by U.S.-based Warner Bros. Discovery ( WBD )

, whose other channels - including news channel TVN24 -

have previously experienced delays to licence renewals in

Poland.

The Polish National Broadcasting Council (KRRiT) said on

Wednesday that a vote on TVN Style's licence renewal was

inconclusive.

"According to the chairman of KRRiT, granting a licence for

the TVN Style program could involve breaking Polish and European

law. For this reason, the company's capital structure will be

subject to a detailed analysis by independent experts," it said.

"Anything that undermines faith in the predictability of the

investment climate in Poland, such as yesterday's statement by

KRRiT questioning the legitimacy of an American company

operating in Poland, undermines our common values, bilateral

interests and the rule of law," US ambassador to Poland Mark

Brzezinski said on X on Thursday.

TVN said in a statement that its ownership structure raises

no doubts, as confirmed by court judgments, numerous legal

opinions and previous decisions of KRRiT granting licences to

its channels.

"The failure to extend the licence for TVN Style and the

comments of the head of KRRiT are another unlawful attack on the

American investor and the values ​​that unite our countries," it

said in a statement on Thursday.

TVN is owned by Warner Bros. Discovery ( WBD ) via a firm registered

in the European Union to adhere to the requirements of a ban on

non-European firms owning more than 49% of Polish media.

TVN24 was criticised by Poland's former nationalist Law and

Justice (PiS) government which alleged that it distorted public

debate by representing foreign interests.

PiS lost power last year, but some of KRRiT members were

nominated by the previous parliament where the PiS party had a

majority in the lower house.

On Thursday, parliament members of the country's ruling

coalition submitted a preliminary motion to bring the head of

KRRiT before the State Tribunal - an arm of the judiciary whose

main task is to enforce compliance with the constitution by the

highest state bodies and officials.

The members of parliament alleged that the head of KRRiT,

Maciej Swirski, has blocked financing for public media and

licences for private broadcasters, including TVN24, among

others.

Swirski was not immediately available for comment.
